| dc.description.abstract | This thesis considers a dual-hop cooperative wireless network consisting of a base station,
intermediate nodes equipped with energy harvesting circuitries, and a legitimate user,
in the presence of a passive multiple eavesdroppers. The intermediate nodes harvest
energy from the base station by using the time switching-based relaying protocol and
use this harvested energy to transmit information to the legitimate user. During the
transmission of information, the BS typically faces a risk of losing information due to
malicious eavesdropping. Thus, to enhance the secrecy of the considered system, one of the
intermediate nodes acts as a jammer, using harvested energy to generate interference with
the eavesdroppers. Under these assumptions, system performance is evaluated in terms
of PLS performance metrics for example Secrecy outage probability, Secrecy throughput
and Asymptotic secrecy outage probability. We present exact numerical and asymptotic
results to justify our analysis. It is seen that as the number of Eavesdroppers increases, the
secrecy performance is deteriorated. Also, as the number of intermediate nodes increases,
the secrecy performance is improved with increasing SNR. Lastly, conclusion and future
recommendations are provided to assist in the succeeding research prospects. | en_US |
